A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to rule this variant out of causing disease. Therefore, this variant is classified as benign.

Department of Pathology and Laboratory Medicine, Sinai Health System RCV001353702 SCV000591545 benign Malignant tumor of breast no assertion criteria provided clinical testing The BRCA1 p.Met1628Thr variant was identified in at least 105 of 111464 proband chromosomes (frequency: 0.001) from individuals or families with breast or ovarian cancer, and was present in 55 of 1140 control chromosomes (frequency: 0.048) (Inoue 1995, Judkins 2005, Ostrow 2004, Phelan 2004, Tavtigian 2006, Tamboom 2010). The variant was listed in dbSNP (ID: rs4986854) “With untested allele”, with a minor allele frequency of 0.004 (1000 Genomes Project); in HapMap-JPT cohort with a frequency of 0.041, and the PAC1 cohort with a frequency of 0.21; and Inoue (1995) found the variant allele at a frequency of 0.39 in a Japanese group of healthy control individuals. The identification of the variant in these population cohorts increases the likelihood that this is a low frequency benign variant in certain populations of origin. The variant was also identified in HGMD, LOVD, the BIC database (96X with unknown clinical importance), and UMD (4X as a neutral variant). In UMD the variant was identified with a co-occurring pathogenic BRCA2 variant (c.4576dup (p.Thr1526AsnfsX3)), and Judkins (2005) observed the variant in trans with three different pathogenic BRCA1 mutations, increasing the likelihood that the p.Met1628Thr variant does not have clinical significance. In addition, a study by Phelan (2004) found that the variant did not segregate with disease in one family, and two functional studies showed no showed no effect of the variant on transcriptional activation (Phelan 2004, Ostrow 2004). Furthermore, Myriad classifies this variant as a polymorphism (personal communication). In summary, based on the above information, this variant meets our laboratory's criteria to be classified as benign.
